Roof flashing has an important job: helping keep water from finding its way into vulnerable areas around vents, pipes, chimneys, and other roof openings. Because it sits where different materials meet, it can face plenty of exposure throughout the year. Understanding what can cause roof flashing to fail helps homeowners and professionals spot potential trouble before a small issue becomes a larger problem.
Weather and Temperature Changes
A roof is exposed to changing conditions throughout the year. Heat, cold, rain, snow, and ice can all put stress on materials around roof penetrations. Repeated expansion and contraction can eventually affect seals and connections, particularly if the flashing wasn’t properly installed or the materials aren’t suited to the application.
Temperature changes can be especially demanding in areas with significant seasonal swings. Even when damage isn’t immediately visible, continued movement can create opportunities for moisture to work its way beneath roofing materials.
Improper Installation
Installation plays a major role in how well flashing performs. If a component isn’t positioned correctly, sealed properly, or matched to the roof and penetration, water may find a path around it. This is especially important around vents and pipes, where flashing must create a dependable transition between the penetration and the roofing material.
The installation process can also create safety concerns. Traditional flashing installation often requires working directly on the roof, which can become more challenging in cold, wet, windy, or steep-roof conditions.
Material Wear and Roof Movement
Flashing doesn’t exist separately from the rest of the roof. As roofing materials age or shift, the areas around penetrations can experience additional stress. Fasteners, seals, and surrounding materials may also deteriorate over time.
Regular inspections can help identify cracked seals, visible gaps, corrosion, or other signs that deserve attention. Finding these problems early can help prevent moisture from reaching the roof deck or entering the building.
A Different Approach to Installation
Kozy Kollar takes a different approach to roof flashing installation. Its flashing systems are designed to be installed from inside the building rather than requiring a worker to climb onto the roof. The products work with several roofing materials and are designed to create a weather-tight seal around exhaust vents and stack pipes.
For professionals looking to reduce the amount of time spent working at roof level while simplifying the installation process, this approach offers another option to consider.
